In a statement on the charity’s website at the time, the SSPCA said Earley had agreed with the charity’s board to leave immediately to allow him to focus on his future plans and so the charity could move forward under new leadership.

Earley had previously faced media criticism for his perceived high wages.

But Earley made complaints of unfair dismissal and discrimination because of disability and age, which were due to go before an employment tribunal before the complaints were withdrawn last month, court papers show.

The SSPCA said the case occurred because of a "misunderstanding" and it had not made any payment to Earley in exchange for the termination of the case.

Harry Haworth, chairman of the SSPCA, said: "There was a misunderstanding after the former chief executive left the society, which was resolved. The tribunal claims were withdrawn. The society did not make any payment in respect of those claims."

Third Sector was unable to contact Earley for comment.

Kirsteen Campbell became chief executive of the SSPCA at the beginning of this month.
